SUPPLEMENT TO AN ANNOTATED CHECKLIST 
OF MISSOURI LEAF BEETLES (COLEOPTERA: 
CHRYSOMELIDAE): NEW STATE RECORDS AND 
HOST PLANT ASSOCIATIONS'^ 

Edward G. Riley, Wilbur R. Enns^ 

ABSTRACT: Fifteen species of leaf beetles (Coleoptera: Chrysomelidae) are reported 
from Missouri for the first time. Significant host data are reported for these and other species. 

Since the completion of our earlier list (Riley and Enns 1979) three 
additional collecting seasons have passed. Collecting efforts during this 
time have been oriented toward specialized plant communities in the more 
outlying areas of the state, particularly glade and prairie habitats of 
southwestern Missouri. The additional field work resulted in the discovery 
of 15 leaf beetle species previously unknown from Missouri. Also reported 
here is one species which was unintentionally omitted from our earlier list. 
These additions bring the total number of chrysomelid species and 
subspecies known from Missouri to 351. Host plant information which is 
new or thought otherwise useful to subsequent investigators is also 
reported. The specimens discussed in this paper are deposited in the 
collection of the first author and the Wilbur R. Enns Entomology Museum, 
University of Missouri-Columbia. 

Cryptocephalinae 

Cryptocephalus calidus Suffrian. NEW STATE RECORD. Missouri 
records: 11 specimens (males) from Boone, Crawford, Livingston, 
Pettis and Phelps Counties, taken in June and July. Due to the difficulty 
in recognizing this species, as mentioned in our earlier paper, we are 
reporting here only records from male specimens. This species is very 
similar in appearance to, and often collected with, Cryptocephalus 
venustus (Fab.). Dr. Richard E. White (USNM) has confirmed this 
determination. 

Cryptocephalus tinctus LeConte. NEW STATE RECORD. Missouri 
records: 13 specimens from Boone, Crawford, and Stone Counties,

taken during August and September. The 12 Boone and Crawford 
County specimens were taken at black lights. 

Cryptocephalus trivittatus Olivier. NEW STATE RECORD. Missouri 
records: 2 specimens from Stoddard County, taken during June by 
sweeping. 



Chlamisinae 

Neochlamisus tuberculatus (Klug). NEW STATE RECORD. Missouri 
records: 3 specimens from Barry County, taken during early June. 
These specimens were collected by sweeping an unidentified Vaccinium 
species growing in a powerline clearcut at Roaring River State Park. 

Eumolpinae 

Colaspis suggona Blake. Adults of this species are very common on prairie 
habitat of southwestern Missouri during early June. Large numbers 
have been encountered defoliating Tephrosia virginiana and Ceanothus 
ova t us. 

Paria sexnotata (Say). In our earlier paper, we reported having seen only a 
single specimen of this species from Missouri, It has since been 
collected by beating Juniperus virginiana, and is especially common in 
May on junipers growing in glade communities (Benton County, near 
Warsaw). The series of specimens available show great variation in the 
pronotal punctation, ranging from deeply impressed, oval punctures to 
semi-strigose or strigose punctures which are often confluent at sides. 
This variability suggests that Paria juniperi Blatchley may not be 
distinct from P. sexnotata. Paria juniperi was described as having the 
pronotal punctures very coarse, confluent and strigose. It is also known 
to occur on Junipems. 



Chrysomelinae 

Calligrapha (Acalligrapha) praecelsis (Rogers). NEW STATE RECORD. 
Missouri records: Three specimens were discovered in the Wilbur R. 
Enns Entomology Museum, UMC, from St. Louis, Missouri (ex G. W. 
Bock collection). One specimen is dated 5-7-94. 

Calligrapha (Calligrapha) philadelphica (Linnaeus). NEW STATE 
RECORD. Missouri records: 24 specimens from Taberville Prairie, 
St. Clair County. These specimens were collected during early May 
from Cornus drummondi.

ENTOMOLOGICAL NEWS 



Calligrapha (Calligrapha) rhoda Knab. Missouri records: 10 specimens 
of this species were collected at Roaring River State Park (Barry Co.) 
during early May from Corylus americana. Blatchley (1910) gave the 
distribution for Calligrapha rhoda var. walshiana Blatchley as Indiana 
and Missouri. Wilcox (1972) also cited this record. These literature 
records were inadvertently omitted from our earlier list. 

Chrysomela lineatopunctata (Forster). NEW STATE RECORD. Missouri 
records: 100+ specimens from Morgan and St. Clair Counties, taken 
during May and June. All specimens, except one, are from Taberville 
Prairie (St. Clair Co.) where they were found breeding on prairie 
willow, Salix humilus, during early May. 

Galerucinae 

Luperosoma parallelum (Horn). This species has been found in large 
numbers on two separate occasions near Warsaw, Missouri (Benton 
Co.) during July. The beetles were feeding on Psoralea tenuiflora. 

Scelolyperus liriophilus Wilcox. This species is more common in Missouri 
than indicated on our earlier list. Records exist (series including males) 
for Barry, Benton, Marion and Taney Counties. The beetles have been 
commonly taken in the Ozark region of the state by sweeping forest 
understory vegetation. They have been repeatedly found on the flowers 
and leaves of smoke tree, Cotinus obovatns, and blattemut, Staphylea 
trifolia , during early May. 

Alticinae 

Kuschelina fimbriata (Forster). NEW STATE RECORD. Missouri 
records: One specimen from St. Clair County, taken during May. This 
specimen was collected while sweeping vegetation of a sandstone glade 
habitat near Collins, Missouri (E.G. Riley colln.). 

Disonycha admirabilis Blatchley. In our earlier paper we reported on 3 
specimens which carried labels reading "on Schrankia 9 . Recent 
collecting has confirmed the beetles’ association with this plant. The 
adults of D. admirabilis are often common in May on Schrankia 
uncinata, especially where it grows on prairie habitat of southwestern 
Missouri. On one occasion larvae were observed in association with 
adults on this plant. 



Chaetocnema alutacea Crotch. NEW STATE RECORD. Missouri

records: 100+ specimens from Vernon County, taken during June. 
These beetles were taken on two separate occasions by sweeping prairie 
habitat near Gay Feather Prairie, 4 miles west of Montevallo, 
Missouri. 

Chaetocnema cribrifrons LeConte. NEW STATE RECORD. Missouri 
records: 60 specimens from Barton, Benton, Callaway, Lawrence, 
Pettis, St. Louis, Taney and Vernon Counties, taken during May and 
June, primarily by sweeping prairie habitat. 

Chaetocnema subviridis LeConte. NEW STATE RECORD. Missouri 
records: 76 specimens from Holt County, taken during June. These 
specimens were collected on two occasions by sweeping grasses 
growing in a cemetery, 1.2 miles south of Mound City, Missouri. This 
area is comprised of loess mound habitat. 

Svstena corni Schaeffer. NEW STATE RECORD. Missouri records: 70 
specimens from Crawford County, taken during August. These speci- 
mens represent a single series which was taken by sweeping dogwood, 
Cornus florida, over a two-day period. The beetles were not abundant. 
Dr. Eric H. Smith (Field Mus. Nat. Hist., Chicago) has confirmed this 
determination. 

Gyptina brunnea Horn. This species has been found feeding on the terminal 
growth of Euphorbia maculata. 

Glyptina cyanipennis Crotch. We recorded this species as feeding on 
Euphorbia dentata in our earlier paper. Since then it has also been 
discovered feeding on Euphorbia heterophylla. 

Glyptina ferruginea Blatchley. A series of 100+ specimens was collected 
in June from Euphorbia obtusata in Randolph County. Damage was 
evident on the plants and the beetles were observed feeding. This is the 
fourth Glyptina species known to feed on Euphorbia . 

Aphthona texana Crotch. NEW STATE RECORD. Missouri records: 6 
specimens from Holt, Lawrence, Pettis and Texas Counties, taken from 
May to July. One specimen is labeled fc4 on red clover \ 

Hispinae 

Anisostena kansana Schaeffer. NEW STATE RECORD. Missouri 
records: 96 specimens from Bates, Dade, Pettis and Vernon Counties,

taken during June and July. These beetles feed on the prairie grass, 
Tripsacum dactyloides. During July, adults, larvae and pupae were 
taken from blotch mines in the leaves of this grass. 

Anisostena nigrita (Olivier). NEW STATE RECORD. Missouri records: 
13 specimens from Barry, Stone and Taney Counties, taken during 
May and June by sweeping grasses of glade communities.
